Most people shopping for a third-party logistics provider start by comparing pick-and-pack rates, because that is the number every 3PL leads with and the only one that appears on all five quotes in the same units. Sixty-eight cents against eighty-one cents feels like a decision you can make.
That belief came from somewhere reasonable. Early fulfillment marketing was built to be compared, and per-order pricing was the one line that behaved like a price tag. But the pick rate typically covers the first item in a box and nothing else. Everything upstream of it and downstream of it is billed separately, and those lines move more than the pick rate ever will.
The work is not finding the cheapest quote. It is learning to read five documents written in five different shapes and see the same warehouse underneath.
1. Receiving, which happens before you have shipped anything
Your inventory arrives at the warehouse before a single order goes out, and that arrival is a billable event. Quotes handle it in one of three ways: per pallet, per carton, or per labor hour. The differences are not cosmetic. A supplier who floor-loads a container instead of palletizing it can turn a tidy per-pallet line into several hours of hand unloading, and you will see that on the invoice a month before you see any revenue.
Ask what counts as a receipt in good condition. Ask whether items arriving without a scannable barcode get labeled by the warehouse, and at what rate per unit. Ask how long receiving takes from the moment the truck touches the dock to the moment the inventory is sellable in the system.
That last answer is the one your buyers feel. A provider that takes five business days to make a restock live is a provider whose backorder emails you will be writing.
2. Storage, billed in a unit you may not be using
Storage is charged by pallet, by shelf, by bin, or by cubic foot, and the unit matters more than the rate. A brand with forty SKUs of small items pays badly under pallet pricing because it is renting height it does not fill. A brand with one bulky product pays badly under bin pricing for the reverse reason.
Three questions separate the quotes that hold up from the ones that do not.
- Is storage prorated, or does an item sitting in the building on the first of the month get charged for the whole month?
- Is there a long-term storage surcharge, and at what age does it trigger?
- Is there a minimum monthly charge, and does spend on other lines count toward it?
Minimums are not a trap. They are how a warehouse covers the fixed cost of keeping your account configured. But a minimum you will not hit for eight months is a real number in your first-year budget, and it belongs in the comparison rather than in a surprise.
3. The second item in the box
The headline pick rate almost always covers one unit. The second and subsequent units in the same order carry an additional pick charge, usually a fraction of the first. Whether that matters depends entirely on your average order composition, which you already know and the 3PL does not.
Take your last few hundred orders. Work out how many units the average one contains. Then price each quote against that mix rather than against a single-item order, and watch two proposals swap places.
The same applies to anything assembled rather than picked. Bundles, subscription boxes, gift sets, anything requiring a unit to be built before it can be shipped: that is kitting, it is usually billed per unit or per labor hour, and it is almost never inside the pick rate. If you sell a holiday bundle, find out now what building ten thousand of them costs and when the warehouse needs the components.
4. Packaging materials and what your buyer opens
Standard corrugated boxes, poly mailers, and basic void fill are usually included or passed through at a modest per-order rate. Custom printed boxes, branded tissue, inserts, gift notes handwritten or otherwise: those are billed, and they are billed twice, once for the material and once for the labor to place it.
This is the line where the customer experience and the invoice meet most directly. The unboxing you designed is a set of discrete warehouse actions, each with a time cost. Price it per order, multiply by your volume, and decide deliberately. Plenty of brands keep the insert and drop the tissue, and no buyer has ever written in to complain about the absence of tissue.
Ask, too, what happens when the right box size is out of stock. A provider that upsizes without telling you is one that quietly raises your dimensional weight on every shipment that week.
5. Shipping, surcharges, and the orders that go wrong
Transportation is generally the largest line on a fulfillment invoice and the one least controlled by the fulfillment quote. What you are actually buying is access to the provider's negotiated carrier rates, plus a rate-shopping engine that picks a service per order. Ask to see a sample rate card for your three most common package sizes to your three most common destination zones. Anything less specific is not comparable.
Carrier surcharges pass through: residential delivery, address correction, oversize, fuel, and peak season adders in the fourth quarter. None of these are the 3PL's doing. All of them are yours to forecast.
Then ask about the orders that fail. Returns processing is billed per return and varies by whether the item is inspected, restocked, refurbished, or disposed of. Find out who answers the buyer's email about a missing package, what the claims process looks like, and what the provider does when it ships the wrong item. The Federal Trade Commission sets the rules governing how promptly merchants must ship what they have advertised, and those obligations stay with you regardless of who is holding the box. A provider with a clear, written exception process is doing part of your compliance work.
Once you have all five quotes rebuilt in your own units, priced against your own order mix, they tend to land within a much narrower band than the pick rates suggested. At that point you are no longer choosing on price. You are choosing on receiving speed, exception handling, and whether the person on the phone in October knows your account.
